Definitions

  • the subject of the present invention is a method of preparation of spherical telithromycin agglomerates and their application in the preparation of pharmaceutical forms.
  • Telithromycin or 11,12-dideoxy-3-de ((2,6-dideoxy-3-C-methyl-3-O-methyl-alpha-L-ribohexopyranosyl) oxy) -6-O-methyl-3-oxo -12,11- (oxycarbonyl ((4- (4- (3-pyridinyl) -1H-imidazol-1-yl) butyl) imino)) - erythromycin is a product with antibiotic structure properties: described and claimed in European patent 680967.
  • the oral route is a preferred form of administration for this product.
  • Telithromycin is an active ingredient that has a bad taste. We must therefore prepare dosage forms which mask the taste of the product and still retain a good bioavailability.
  • telithromycin The physico-chemical qualities of telithromycin are such that they allow micro-encapsulation, i.e. coating the active ingredient with a polymer or blend of polymers.
  • Micro-encapsulation can be carried out by spraying of a polymer or by interfacial polymerization or by coacervation.
  • a polymer or by interfacial polymerization or by coacervation.
  • the particles must be spherical so that the covering of the active ingredient by the polymer be correct and to get good kinetics of release of the active ingredient.
  • Spherical agglomerates are obtained by transformation direct spherical cluster crystals and the subject of the invention is therefore a method of preparation of spherical agglomerates characterized in that one prepares a suspension of telithromycin crystals, then coats these crystals of a phase insoluble in telithromycin which gradually crystallizes.
  • the subject of the invention is in particular a method of preparation characterized in that a solution is used of telithromycin in acetone.
  • the subject of the invention is more particularly a preparation process characterized in that the crystallization takes place in an acetone / ether mixture isopropyl.
  • the crystallization is carried out between -5 and -15 ° C.
  • the size of agglomerates spherical is controlled by adjusting the stirring speed.
  • the agglomerates according to the invention allow good microencapsulation and the subject of the invention is in particular the application characterized in that we surround the spherical agglomerates of a polymer layer to obtain the dosage form sought, for example microcapsules.
  • the spherical agglomerates of telithromycin obtained according to the invention are characterized in that the size of the particles is between 30 and 400 microns and in particular in that the median particle size is between 80 and 150 microns.
  • the spherical agglomerates of preferred telithromycin are characterized in that the size median of the particles is located around 100 microns, that is to say characterized in that half of the agglomerates have a size less than 100 microns.
  • Agitation is carried out under a slight nitrogen overpressure between 19 ° C. and 21 ° C and verifies that the dissolution is complete.
  • the temperature is stabilized between 19 ° and 21 ° C.
  • the mixture is stirred for 15 minutes at 20 ⁇ 1 ° C. and then the suspension at -10 ⁇ 1 ° C in 30 minutes.
  • the mixture is still stirred for 1 h at -10 ° C.
  • telithromycin 50.4 g of spherical agglomerates are obtained.
  • Particle size is determined by diffraction laser using a HELOS SYMPATEC® granulometer.
  • the product of the example was used to prepare by simple coacervation or by direct spraying of a suitable polymer for microcapsules intended for preparation of oral suspensions to be prepared immediately.
